5 Written questions

5 Matching questions

  1. annulus
  2. pericardial tamponade
  3. prevent relapse of valve cusps into atria (when the ventricles and papillary muscles contract the chordae tendonae are pulled tight preventing prolapse of valve cusps/leaflets into the atria)
  4. the brain and right arm
  5. fibrous pericardium
  1. a what is the function of chordae tendonae
  2. b abnormally increased fluid volume in the pericardial space
  3. c fibrous tissue ring that forms the base of each heart valve
  4. d what are the regions supplied by the brachiocephalic trunk
  5. e what is a non-elastic tissue layer that composes the outermost layer of the pericardium. it is visible when the chest is opened

5 Multiple choice questions

  1. when the atria contract which valves are open
  2. what is the shape of the right ventricle
  3. list the 3 aortic arch vessels
  4. Contraction of the inter-ventricular septum facilitates ejection of blood from which heart chamber
  5. this is an electrical short cut that conducts myocardial action potentials rapidly fron the inter ventricular septum to the papilllary muscles on the lateral side of the right ventricle

5 True/False questions

  1. pericardial spaceabnormally increased fluid volume in the pericardial space

          

  2. the tricuspid and mitral valves close when the blood pressure within the ventricles exceeds blood pressure within the atriabriefly describe the mechanism of AV valve closure

          

  3. epicardium, visceral pericardiumwhat is a non-elastic tissue layer that composes the outermost layer of the pericardium. it is visible when the chest is opened

          

  4. from the superior,inferior vena cavas, and coronary sinus into the right atrium, through the tricuspid and into the right ventricle, through the pulmonary valve, into the pumonary trunk, into the pulmonary arteries and into the lungs. oxygenated blood from the lungs passes through the pulmonary veins into the left atrium, through the mitral valve and into the left ventricle, through the aortic valve and into the ascending aortabriefly describe the tricuspid valve

          

  5. endocardiumname the innermost layer of the heart wall
